Uh oh.

You really don't want puppies. Puppies are not a good thing to bring into this world at this point in time! Do you know how many dogs are put to sleep in animal shelters every year? If you let your dog breed and then even one of her pups breeds, and then even one of those pups breed - pretty soon you have an awful lot of poor little homeless doggies out there.

You have to be EXTREMELY careful! I know of a female dog who got pregnant THROUGH THE CHAINLINK FENCE! When they want to get together, dogs can be extremely creative!

If it's a $ issue, call your local animal shelter. They might be able to point out some inexpensive places to have her spayed, or give you a coupon or something.

The damage which would be done by letting her get in contact with an unaltered male would be much greater than any damage of not allowing her to play with him!
